Explain how prebiotics and probiotics work?

Probiotics are supplements of bacteria that is good for the GI tract (so called "good bacteria"). A common formula of probiotics is called PB-8. There are many formulas of probiotics. Each formula has a different strain or strains of bacteria that is known to be "good." By "good" they mean that these bacteria are either helpful in digestion OR they cause the "bad" bacteria to be less in number.

What is the chemical name of antibiotic?

There are many different kinds of antibiotics that contain different substances. In simple terms, an antibiotic is a medical substance derived from chemical preparations, organic preparations, etc. that have been proven to kill bacteria, usually each type of antibiotic is targeted at specific types of bacteria since not all antibiotics are effective against all bacteria. The substances usually destroy the organism's cell walls so they can no longer function, or damage the ability of the bacteria to reproduce. They destroy them or inhibit the growth and/or functions of these harmful microorganisms.

What is specific growth rate constant?

it is used as a way of measuring how fast cells are dividing, defined as the doubling rate, and it is worked out with the following formula: k=(Log Nt - Log No)/ t x Log 2 this goes to the slightly easier form of; k= 3.32 x (Log Nt - Log No)/ t where k= growth rate constant Nt = number of bacteria at second time No = number bacteria at start t = time gone. (obvioulsy you take the logs of Nt and No in the formula)

Might pasting in excel with relative references ever produce the wrong result?

Yes. It depends on the formula and what you want the formula to do. So it is easy to have the wrong formula and paste it, or have the correct formula initially, but when it is pasted elsewhere it does not use the correct values. Normally if you have your worksheet set up correctly then once the initial formula is correct, pasting it to the right place should not cause any problems.
